Yup, that's connected to the Returnpath feedback loop, rather than  
reputation tracking. They're allowing you to sign up for a feedback  
loop for a particular d= value and for either one specific selector or  
all selectors.

When tracking specific issues it may well be useful to get FBL reports  
for just one specific user of a DKIM identity, and being able to key  
on selector seems a good enough way to do that, if a bit of a hack.  
It's not something I'd expect anyone to use normally, though.

I don't believe that Yahoo are using the selector for anything  
reputation related, though, and I wouldn't expect them to do so in  
general. (Not ruling out some ESP-specific hack, if it turned out to  
provide them with useful data, but that would be a private hack rather  
than anything more).

RP or Yahoo might be able to be more authoritative on that.

Cheers,

Hi,

I see some ESP are using the selector to do domain reputation.

In what way? Given that the selector is an opaque string, are you
reading something into their choice of selectors that isn't there, or
are they documenting that they intend meaning for their selectors?
